Long term complications of concussion include:
- Post-concussion syndrome. This is a condition in which you experience concussion symptoms for weeks or even months (instead of days) after experiencing a concussion. Such symptoms may include ongoing dizziness/spinning, headache, memory and concentration problems, mood swings, depression, anxiety, irritability, personality changes, insomnia (can’t sleep) and excessive drowsiness.
- Higher risk of anxiety and depression (especially if there’s been multiple concussions).
- Structural brain injuries from multiple concussions. People who have had several head injuries in their life are at higher risk of long-lasting impairment. Chronic traumatic encephalopathy is one example of a brain condition linked to repeated blows to the head.
- Problems with memory, naming and word-finding.
Anyone who has symptoms that won’t go away or that are worsening seen be seen by their healthcare provider.
